Usually, a hard iron material is only required if your non-clog pump utilizes a semi-open impeller. A semi-open impeller does not have a shroud on the suction side and rotates against an adjustable suction wear plate, which results in a high amount of wear on the impeller. Semi-open impellers rely on a sharp leading edge to cut material in the ...
